[0034] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0035] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0036] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or selectively exclusive embodiment from other embodiments.

[0037] As shown in the Figure 1 and the Figure 3 accompanying drawings:

[0038] Embodiment 1: This embodiment provides a vital sign monitoring and warning device, including a bracelet main body 1 and a quick wearing mechanism 2; a vital sign monitoring component is arranged inside the bracelet main body 1; the quick wearing mechanism 2 includes elastic clamps 201 arranged on both sides of the bracelet main body 1, a pulling rope 202 is arranged on the outer side of the elastic clamp 201, activity slots 204 are arranged on both sides of the bracelet main body 1, a pressing rod 203 is movably arranged in the activity slots 204, one end of the pulling rope 202 is connected to the lower end of the elastic clamp 201, and the other end of the pulling rope 202 is connected to the front end of the pressing rod 203.

[0039] When the patient wears it, just use the spare hand to hold the bracelet body 1. The operation of holding is as follows: Use two fingers to press against the two pressing rods 203 respectively and apply pressure to increase the friction between the fingers and the bracelet body 1, so as to pick up the bracelet body 1. Since applying pressure to the pressing rod 203 will push it deep into the movable slot 204, the pressing rod 203 will push the pull rope 202 to move at the same time, and then pull the lower end of the elastic clamp 201 through the pull rope 202. The elastic clamp 201 is in a U-shaped initial state. Pulling the lower end of the elastic clamp 201 will make its opening larger, so that it unfolds and increases the gap between the two elastic clamps 201. At this time, the bracelet body 1 can be easily placed on the wrist of the wearing hand. At this time, the bottom of the bracelet body 1 contacts the skin on the surface of the wrist. Then release the pressing rod 203, and the elastic clamp 201 will deform towards the initial state by its own elasticity. During the process, it will be stuck on both sides of the patient's wrist to complete the wearing of the bracelet body 1. When the elastic clamp 201 deforms and resets, it will pull the pull rope 202 to move in the initial direction, and then pull the pressing rod 203 to move out of the bracelet body 1, which is convenient for pressing the pressing rod 203 again when the bracelet body 1 needs to be removed later.

[0040] During the process of the staff holding the bracelet body 1, the elastic clamp 201 can be opened, and the elastic clamp 201 will automatically close after being released. It can be used with one hand without the assistance of others, which is convenient for personnel to use. And when the patient is uncomfortable, the patient can quickly break free from the elastic clamp 201 and get off the wrist, and the disassembly and assembly are fast.

[0041] As shown in the Figure 3 and Figure 4 figure:

[0042] Specifically, a pressure sensor 207 is arranged in the movable slot 204 at the front end of the pressing rod 203. Limit blocks 205 are arranged on both sides of the pressing rod 203, and a spring 206 is arranged between the limit blocks 205 and the movable slot 204.

[0043] When the person presses the pressing rod 203 to open the elastic clamp 201 for disassembly and assembly of the bracelet body 1, the front end of the pressing rod 203 will squeeze the pressure sensor 207. After the pressure sensor 207 detects the pressure, it will transmit the pressure signal to the bracelet body 1 for processing, so as to transmit the opening information of the bracelet body 1 to the medical staff, so that the medical staff can know that the bracelet body 1 has been removed in the first time.

[0044] When the patient actively removes it, they will hold down the pressing rod 203 for a long time, and the detected pressure signal is long in time and large in pressure. When the patient pulls the bracelet main body 1 due to blurred consciousness or accidentally drops it, they will not hold down the pressing rod 203. The elastic clamp 201 will be forcibly pushed open, causing the pulling rope 202 to slacken. The spring 206 will pull the pressing rod 203 deeper into the movable slot 204 due to the slackening of the pulling rope 202, causing it to contact the pressure sensor 207. When the elastic clamp 201 is separated from the wrist and reset, it will quickly separate from the pressure sensor 207. At this time, the detected pressure signal is short in time and small in pressure. Based on this, it can be judged whether the patient removes it actively or due to an accident, so as to facilitate the medical staff to prepare in advance and deal with it in a timely manner.

[0045] As shown in the Figure 5 attachment:

[0046] Specifically, the vital sign monitoring component includes a microprocessor 101, a communication module 102, an electrocardiogram sensor 103, a temperature sensor 104, a blood pressure sensor 105, a blood oxygen sensor 106, a three-axis sensor 107, and a positioning module 108. The microprocessor 101 is electrically connected to the communication module 102, the electrocardiogram sensor 103, the temperature sensor 104, the blood pressure sensor 105, the blood oxygen sensor 106, the three-axis sensor 107, the pressure sensor 207, and the positioning module 108 respectively to realize the acquisition and processing of data from each sensor and communication with external devices.

[0047] The electrocardiogram sensor 103 is used to collect the electrocardiogram signal of the human body, such as the TIADS1291 type sensor. The temperature sensor 104 is used to measure the body temperature of the human body, such as the MAX30205 type sensor. The blood pressure sensor 105 is used to detect the blood pressure value. The blood oxygen sensor 106 is used to monitor the blood oxygen saturation, such as the MAX30100 type sensor. The three-axis sensor 107 can sense the motion state and posture of the human body, such as the ADXL345 type sensor. The positioning module 108 is used to determine the position information of the wearer, such as the Beidou positioning sensor.

[0048] As shown in the Figure 1 and the Figure 2 attachment:

[0049] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the monitoring and warning device further includes a fixing mechanism 3. The fixing mechanism 3 includes fixing belts 301 arranged on both sides of the bracelet main body 1. A restraint belt 302 is arranged on one of the fixing belts 301. The front end of the restraint belt 302 penetrates through the other fixing belt 301, and magic tapes 305 are arranged at both ends of the restraint belt 302.

[0050] The fixing band 301 is located inside the elastic clamp 201. When the elastic clamp 201 clamps the wrist, the fixing band 301 serves as a buffer layer between the clamp and the skin, enhancing the wearing comfort. When a patient who needs to wear and use the device needs to perform extensive physical activity training or has restlessness, the restraint band 302 is passed through another fixing band 301, and then the restraint band 302 is pulled to tighten it. Then, the front end of the restraint band 302 is connected to its rear end through the magic tape 305, so that the device is bound to the patient's wrist by the fixing band 301, greatly improving the wearing stability and effectively preventing it from falling off during training or restlessness.

[0051] Specifically, bumps 304 are provided on the fixing band 301, an elastic band 303 is provided on another fixing band 301, and through holes 306 are provided on the elastic band 303. The through holes 306 are adapted to the bumps 304.

[0052] After the restraint band 302 is passed through another fixing band 301, the elastic band 303 is pulled so that it is buckled on the bump 304 through the through hole 306, thereby connecting the two fixing bands 301 together by the elastic band 303. The elastic band 303 will use its own elasticity to pull the two fixing bands 301 closer to each other, so that they are closely attached to the patient's skin to achieve preliminary fixation. Then, the front end of the restraint band 302 is connected to its rear end through the magic tape 305 to achieve complete fixation. The elastic band 303 will adapt to the thickness of the patient's wrist with its own elasticity, and the restraint band 302 does not need to be tightened and adjusted, avoiding the discomfort or loose instability caused by manual adjustment being too tight, which is convenient for personnel to use.

[0053] As shown in the Figure 6 attachment:

[0054] Embodiment 3: This embodiment provides a vital sign monitoring and warning system, which includes the above-mentioned vital sign monitoring and warning device, and further includes:

[0055] A data management module, which is used to record the basic information of the patient and obtain the real-time vital sign information of the patient;

[0056] The basic information of the patient includes name, age, gender, medical history, allergy history, etc. The real-time vital sign information is obtained through the vital sign monitoring component, including electrocardiogram, body temperature, blood pressure, blood oxygen saturation, motion state, and position information, etc., and these data are stored and managed.

[0057] A data analysis and processing module, which is used to preset the normal threshold range of vital signs according to the basic information of the patient, and process and identify the real-time vital sign information of the patient to judge whether there is an abnormality;

[0058] Preset the normal threshold range of vital signs according to the patient's basic information, process and identify the patient's real-time vital sign information, and judge whether there are abnormalities, including:

[0059] According to the patient's basic information, construct an individual characteristic model of the patient through the decision tree algorithm;

[0060] This model can reflect the individual differences and unique physiological characteristics of the patient.

[0061] Using the patient's historical vital sign data and the statistical data of the same type of patient group, and integrating medical expert knowledge and clinical experience at the same time, set the normal threshold range of vital signs by using the mean plus or minus the standard deviation;

[0062] The threshold range set in this way takes into account both the historical data of the patient's individual and the statistical laws and medical professional knowledge of the same type of population, and has high scientificity and rationality.

[0063] Compare the collected real-time vital sign data of the patient with the preset normal threshold range of vital signs, and calculate the deviation value of each vital sign index from its corresponding normal threshold through the difference calculation method;

[0064] Use this to judge whether each index is within the normal range.

[0065] According to the change situation of the patient's recent vital sign data, use the adaptive weighted average algorithm to dynamically update the vital sign threshold range in real time.

[0066] As the patient's physical condition changes, the threshold range can be adjusted in time to ensure the accuracy and effectiveness of monitoring.

[0067] An early warning module for triggering an early warning when an abnormality is judged.

[0068] Triggering an early warning when an abnormality is judged includes:

[0069] When a single index in the patient's real-time vital sign information exceeds the preset normal threshold range of vital signs, start the local audible and visual alarm;

[0070] Remind the patient or the people around by the micro audible and visual warning device located on the bracelet body 1 of the current abnormal situation of the vital signs.

[0071] When at least two indexes in the patient's real-time vital sign information exceed the preset normal threshold range of vital signs, send the early warning information and the current real-time vital sign information of the patient to the department management terminal.
